Answer 1

$\huge\boxed{\fcolorbox{syam}{yellow}{Answer}}$

$\huge\mathsf{\underline{\red{Isotopes}}}$

→ Each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.

$\huge\mathsf{\underline{\red{Isobars}}}$

→ Each of two or more isotopes of different elements, with the same atomic weight.
